Abstract: A privileged account management system can detect when credentials used to access one or more servers have been shared or otherwise compromised. This detection can occur through analysis of simultaneous actions that are performed via multiple sessions associated with the same administrator. When two or more sessions associated with the same administrator are opened, the interactions performed over each of the sessions can be monitored to identify whether such interactions could be performed by a single administrator. If it is determined that the interactions over the multiple sessions could not reasonably be performed by a single administrator, various actions can be taken to address the possible breach to the security of the one or more servers.

Abstract: In one embodiment, a method is performed by a computer system. The method includes discovering content in a user environment. The method further includes generating one or more content fingerprints on a per-content basis. The method also includes providing information sufficient to identify the one or more content fingerprints to a central computer system. Further, the method includes receiving a user selection of particular content stored in the user environment. In addition, the method includes requesting, from the central computer system, information related to a level of exposure of the particular content across a plurality of platforms and a plurality of users. Moreover, the method includes receiving exposure information for the particular content in response to the request. Additionally, the method includes publishing the exposure information to a user associated with the user environment.

Abstract: Innovative technologies for reducing network request response times over a server-signed connection are disclosed. The technologies may involve dynamically computing synchronized compression dictionaries using server responses to speculative or “read-ahead” client requests. The technologies operate even when the client is unable to accept the server responses due to server-signing constraints. A server proxy may receive a read-ahead request originating from a client proxy. After receiving a response to the read-ahead request from a server, the server proxy may populate a compression dictionary and forward the read-ahead request to the client proxy. The client proxy may populate its own synchronized compression dictionary using the forwarded read-ahead response. The server proxy and client proxy may use the compression dictionaries to respectively compress and decompress a response to an actual client request that matches or is highly similar to the earlier response to the read-ahead request.

Abstract translation: 披露了通过服务器签名连接减少网络请求响应时间的创新技术。 这些技术可能涉及使用对投机或“预读”客户端请求的服务器响应动态计算同步压缩字典。 即使客户端由于服务器签名限制而无法接受服务器响应，这些技术也会运行。 服务器代理可以接收来自客户机代理的预读请求。 在从服务器接收到对预读请求的响应之后，服务器代理可以填充压缩字典并将预读请求转发给客户端代理。 客户端代理可以使用转发的预读响应填充其自己的同步压缩字典。 服务器代理和客户端代理可以使用压缩字典来分别压缩和解压缩对与预读请求的较早响应相匹配或高度相似的实际客户端请求的响应。

Abstract: A method for determining mail archive ownership during data migration is described. The method is performed by a Migration Manager that is capable of generating a list of possible owners based on confidence level. The confidence level is obtained by scanning various messages associated with the mail archive and determining a frequency of appearance a particular user name (e.g., e-mail address) appears compared to the total number of messages scanned. The generated list of possible owners can subsequently be used to determine/confirm the owner of the mail archive. Confirmation may be required before the data migration is completed.

Abstract: A method for migrating a nickname cache via a migration manager is described. The method includes the migration manager locating where the nickname cache is stored and locating where the nickname cache is to be migrated. Once the source and target devices are located, the migration manager can generate any necessary transformations so that the data migrated from the source device to the target device is compatible. The nickname cache can then be extracted from the source device, transformed and stored into the nickname cache of the target device.

Abstract: Techniques and mechanisms described herein facilitate the encryption of content using content-based encryption keys. According to various embodiments, data stream may include one or more data chunks. A client machine may apply a hash function to a data chunk to determine a fingerprint value. A cryptographic protocol shared with a remote server may be applied to the fingerprint value to determine a data chunk encryption key. The data chunk encryption key may be used to encrypt the data chunk, and the encrypted data chunk may be sent to the remote server for storage.

Abstract: The present invention relates to a method and system for performing deep packet inspection of messages transmitted through a network switch in a Software Defined Network (SDN). Embodiments of the invention include a network switch, a controller, and a firewall in a software defined networking environment. In the present invention, the network switch is a simple network switch that is physically separate from the controller and the firewall. The invention may include a plurality of physically distinct network switches communicating with one or more controllers and firewalls. In certain instances, communications between the network switch, the controller, and the firewall are performed using the Open Flow standard communication protocol.

Abstract: When a user receives potential junk e-mail from an unknown sender address, an active filter installed in or cooperating with the user's e-mail system sends a challenge e-mail back to the sender address. Unless the user receives a correct response e-mail from the sender address and/or a response that meets formal criteria, the active filter rejects the original e-mail and blocks future e-mail from that sender address. The challenge preferably includes a question that the sender must correctly answer in his response. The question is such that only humans can interpret and respond to it correctly. For example, the question may relate to and/or be incorporated in an image in the challenge. Lists of approved and blocked sender addresses are compiled. The user may directly enter addresses in the address lists. Addresses to which the user has sent e-mail may also be included directly in the approved list.
